FAQs

Q: Is the 9455P compatible with dual-socket motherboards?
A: No. The P-suffix indicates single-socket only (1P). It must be used in a 1P SP5 platform.

Q: What cooling solution is required?
A: Use the server’s qualified SP5 heatsink and thermal solution rated for a 300W TDP CPU.

Q: What memory is supported?
A: 12-channel ECC DDR5 RDIMM/LRDIMM. Achievable data rates depend on DIMM population and platform; up to 6000 MT/s is platform dependent.

Q: How many PCIe lanes are available?
A: Up to 128 lanes of PCIe 5.0, with CXL support, subject to platform design.
